OSCAR MUSSINAN, JR.,

- UNITED STATES PATENT O-FFICE OF NEW YORK, N. Y., AssIGNORTO E ERHARD FABER, OF SAME ACE.

PENCIL.

SPECIFICATION forming part of Letters PatentNo. 382,488, dated May 8, 1888.

u Application filed February 3, 1898.- Serial Ko. 262,E66. (No model.)

' tubular body or sheath for the separate Inovable lead, which body is slotted in part of its length, a slotted tubular holder for the end of the separate lead, with which holder is formed a toothed plate traveling in the slot of the tubular body Or sheath, a loose Sheet-metal cylindrical screw surrounding thesaid body, into which the tceth of the toothed plate mesh, said Sheet-metal cylindrical screw becoming the Inotor to propel and repel the lead andsurrounding the tubular body or sheath, and

at each end of the Sheet-metal cylindrical screw is a metal ring to confine and prevent lateral movementto the Sheet-metal cylindrical screw as it is revolved to propel or 'repel thelead.

In the drawings, Figure 1 shows by a longitudinal section an adaptation of my 'improvement to a cheaplymade pencil, and Fig. 2 is a cross-section at the line w x. Figs. 3 and 4 show by longitudinalsections the adaptation of my'improvement to more eXpensively-made pencils, and Figs. 5 and 6 are cross sections at the lines y y and z 2.'

a represents the tubular body or sheath, which in all cases I prefer to make of wood and to slot centrally for part of its length, as shown in the cross-sections, Figs. 2, 5, and 6. This tubular body or sheath a, as shown' in Fig. 1, becomes the handle of the pencil, and its surface may be finis'hed in any 'desired manner, the point beingadapted to be cut away as the lead comes down to its full propel position.

b represents the separate removable lead, the inner end of which iS received in and grasped by the'slotted tubular metal holder c, which holder is made with a toothed plate, G', and connecting-bar 1, the toothed plate c' traveling in the slot of the tubular body a.

surrounding the tubular body a is a loose holder c, and lead b being caused to move in either direction by the rotation of said screw, the plate remaining in the slot 2, and the movement being determined by the length of the slot.

drical screw d,-secured to the body a, which contine and-prevent any lateral movement of There are metal stop rings or collars e V f, one atjeach end of the Sheet-metal cylln 6 the same along the tubular body as the lead is propelledorrepelled. The collar or ring f, I

prefer to make sufficiently long to hold'an erasing-rubber in its outer' end. r

-The form of pencil shown in Figs. 3 and 5 differs from that shown in Figs. 1 and 2 in the length of the Sheet-metal cylindrical screw d, which here becomesa handle to the pencil, and in the fact that the end of the tubular slotted body a is pointed and not adapted to be cut away, thelead being propelled as used until used up, when the end of the slotted tubular holder c Will project beyond the point sufliciently for a new lead to be inserted therein. The form of pencil shown in Figs. 4 and 6 differsfrom the others in'the following details of construction: A metal tube, h, surrounds the tubular slotted body a, and it, as well as the *I body, is slottedfor the toothed plate c A metal point, Z, is securedto the ring e, and a metal cap, k, is Secured to the ring f. This slotted metal tube h could be used in the forms of. pe'ncils shown in Figs. 1, 2, 3, and 5 with equal facility. i

Although I have shown several forms of pencils to which -Iny invention is adapted, yet

the essential features arepreserved in alle viz., a tubular body Or sheath that is slotted in part, a removable lead, a tubular holder for the end of the lead, a .toothed plate traveling in said slot, a Sheet-metal cylindrical screw V i around the tubular body, and stop rings or collars, one at each end of the sheet-metal cylindrical screw, which Sheet-metal screw ln all cases becomes-the motor to propel and repel the lead.

IOO

I Claim as my invention- 1. Inapencil, the combination of a tubular slotted body, a. slotted tubular holder for one end of the lead, a toothed plate projecting from Said holder, a Sheet-metal cylindrical ScreW around the tubular body, and into which the teeth of the plate mesh, and collars or rings around the body at the ends of the cylindrical Sheet-metal ScreW, Said SereW becoming the motor in a propel and'repe] pencil, substantialy as Specifie f o 2. In a pencil, the combination of a tubuia body or Sheath, a, slotted centrally for part of its length, the slotted tubular holder c for one end of thelead, the toothed plate c', projecting -from said holder, the Sheet-metal eylindrical screw d, the metal ring or collar 6 at one end of Said ScreW d, and the metal ring or collarf at the other end of the same, Said collarf being extended as a Sleeve and adapted to hold 20 an erasing-rubber, Substantially as specified.

3. In a pencil, the combination of a tubular body or Sheath, a, slotted centrally for part of its 1ength,' the slotted tubular holder 'c fox' one end of the lead, the toothed plate c', formed 2 with Said holder, the Slotted metal tube h, Surrounding the tubular slotted body a, the sheetmetal cyiindrical screwd, and the metal riugs or collars e f around the body at the ends of the cylindricai ScreW, substantially as and for 30 the purposes set forth.
